Wisdom gets half of its value from its being useful, and the other half from the being of at least one fool.

Sometimes a fool says something wise without the intention to do that, and the awareness of having done that.

Fools already disagree with what their enemies have not yet said.

Only a fool would speak of their impatience or intolerance with pride.

Being deemed a fool, even if it is done by a fool, does not hurt, unless you are a fool.

Never argue with a fool. People may realize or remember that you are one.
